Definitions

  • the invention relates to the field of medicine and, more specifically, it relates to the stomatology and is intended for cleaning the interdental spaces with simultaneous massage of the gingiva for the purposes of improving the hygienic condition of the oral cavity and preventing stomatological diseases.
  • dental sticks with cleaning elements deflected from the holder axis EP 0932371 , SU 1627166 ), with a curved holder and pointed cleaning elements ( DE 2915044 ).
  • a common disadvantage of these dental sticks is the impossibility or difficulty of a simultaneous massage of the gingiva between teeth.
  • a dental stick-activator containing a straight, unbent holder with oppositely deflected massaging and cleaning elements tapered towards the ends thereof while forming in each massaging element a cross-trapezoidal section with cleaning elements 3 at their end which are deflected from the holder plane in opposite directions
  • PCT/RU95/00274 published as WO 96/19155 .
  • the main disadvantage of the known dental sticks is the difficulty of massaging the gingiva, particularly their remote parts. Besides, the trapezoidal shape and a variable size of the cross-section of the massaging and cleaning elements complicate the process of producing the articles.
  • US-A-5 806 540 discloses a tooth pick having a hollow body with an internal rib which forms a cleaning element in a head part with a tip which is an extension of the rib and arranged rectangular to the straight, bendable body of the tooth pick.
  • a sealing wall seals air in the hollow body.
  • the basic object of the invention is to develop a dental stick simple in design and providing a possibility of cleaning and massaging the interdental space with simultaneous massage of the gingiva front surface.
  • a dental stick comprising a holder with massaging and cleaning elements at both ends of the holder, which are directed in opposite directions and tapering towards their ends
  • the holder is curved so that an inflection is formed in its middle section with two adjacent symmetrical segments which are offset on opposite sides relative to the axis of symmetry of the dental stick.
  • the massaging elements have two flat surfaces extending perpendicular to the plane defined by the curved holder, the massaging elements pointing in a direction opposite to the offset direction of the adjacent symmetrical segment of the holder.
  • the cleaning elements are formed at the edges of the massaging elements with extensions directed towards opposite sides relative to the plane formed by the curved holder.
  • the cross-sections of the symmetrical segments of the holder are circular and decrease so that said segments taper in the direction from the center of the holder towards the massaging elements.
  • the massaging elements have a surface opposite to the direction of the extension of the corresponding cleaning element, said surface being wave-shaped.
  • the symmetrical segments of the holder are made arc-shaped, coupled to each other and have their convex portions directed in opposite directions, or they are made rectilinear coupled to each other through a curved portion.
  • the rectilinear portions of the holder are parallel to its axis of symmetry.
  • the extensions of the cleaning elements are rounded.
  • each massaging element enables one to perform pulsating pressure on the soft tissues of the gingival papilla, thereby causing an excessive blood supply to these areas and, therefore, to increase the massaging efficiency as a whole.
  • the dental stick comprises a holder 1 with a massaging element 2 and cleaning element 3.
  • the holder 1 is bent with an inflection in the middle section to form two symmetrical segments 4 and 5 which are offset on opposite sides relative to the axis of symmetry 6 of the dental stick.
  • the symmetrical segments of the holder 1 are arc-shaped symmetrical segments coupled to each other, and their convex portions are directed in opposite directions.
  • the cross-sections 7 of the symmetrical segments of the holder 1 are made circular and decrease so that said segments taper in the direction from the middle of the holder towards the massaging elements.
  • the massaging and cleaning elements 2, 3 are tapered in the direction towards the ends of the cleaning elements and have two flat surfaces 8 and 9 perpendicular to the holder axis plane 10.
  • the massaging elements 2 are deflected in the directions opposite to the offset portions of the symmetrical segments 4 and 5 of the holders relative to the axis of symmetry 6.
  • the cleaning elements 3 have arc-shaped extensions 11 which are directed to opposite sides relative to the axis plane of the holder 10.
  • the surfaces 12 of the massaging elements opposite to the direction of the extension 11 of an appropriate cleaning element are wave-shaped.
  • the dental stick may be made of stainless steel or high-strength plastic. All joining parts of the dental stick should be rounded to reduce its internal stress and to exclude a possibility of damage of the paradontium tissue.
  • the dental stick is used as follows. One of the symmetrical segments of the holder with the massaging element is clipped by three fingers of the right hand. If in this case the other massaging element is directed downwards, the top right or bottom left sides of the jaw is treated. In the space between the adjacent teeth the cleaning element 3 is inserted and then the massaging element 2 and a few movements are made across the jaw and up-and-down with a slight pressure on the gingiva between the teeth that allows one to remove the remnants of food and, at the same time, to perform the massage of the gingiva and gingival papilla. After that the dental stick is taken for the other end and perform the treatment of the left half of the top jaw and the right half of lower jaw.
  • the invention can be widely used in the medical-dental practice as means of individual hygiene allowing one to reduce inflammatory processes in paradontium tissues, to stop gingiva angiostaxis, to reduce the teeth mobility, to improve a trophism of blood vessels and activity of the paradontium nervous system.
